An interesting BBC video on dynamical systems, created by Lasse Rempe of the University of Liverpool.
http://news.bbc.co.uk/1/hi/sci/tech/7617191.stmAn interesting introduction to dynamical systems is David Luenberger's Introduction to Dynamical Systems: Theory, Models and Applications. (David is a professor of management science and engineering at Stanford and has published lots of articles in journals like "IEEE Transactions on Automatic Control" and "SIAM Journal on Control and Optimization").
Here is an interesting edition of the IEEE Automatic Control journal focusing on Systems Biology.
